This text addresses imbalances between availability and demand, degradation of surface and ground waters, inter-sectorial, inter-regional and international competition in water management. With contributions from international experts at the 1st Inter-Regional Conference on Environment-Water: Innovative Issues in Irrigation and Drainage. The book should be of use to policy makers, planners, irrigation engineers, researchers, and post-graduate students specialising in irrigation and canal engineering, water pollution and water quality. It should also be of interest to libraries and...

Agriculture in Sub-Saharan Africa is constrained by highly variable rainfall, frequent drought and low water productivity. There is an urgent need, heightened by climate change, for appropriate technologies to address this problem through managing and increasing the quantity of water on farmers' fields - water harvesting. This book defines water harvesting as a set of approaches which occupy an intermediate position along the water-management spectrum extending from in situ moisture conservation to irrigated agriculture. They generally comprise small-scale systems that induce, collect, store...
